| 摘 要： | 导航电文的生成是GLONASS卫星信号模拟器研制中的关键部分,获得正确的导航电文信息是接收机实现定位、测速以及授时等功能的前提条件。为了满足接收机测试的需要,GLO-NASS卫星信号模拟器输出信号必须调制正确的导航电文。GLONASS卫星信号模拟器由模拟器仿真软件和信号生成单元组成。主要研究GLONASS卫星信号模拟器的软件部分。在分析GLONASS卫星信号模拟器结构和导航电文结构的基础上,详细介绍了GLONASS卫星信号模拟器中导航电文的生成过程。重点对从R inex文件中读取星历参数并转化成二进制格式导航电文的程序实现进行了深入研究,利用GLONASS接收机对卫星信号模拟器输出的仿真信号进行电文解析和定位解算,试验结果可以验证卫星信号模拟器中导航电文生成的正确性。
